- To all whom Jitv 'may concern:

Y Beit known that I, W. SMITH', of San Francisco, in the county of San Francisco, and'State of California, have invented 'certain new and useful Improvements in Valves for Water-Olosets `and I do hereby declare that the following is a full and exact description of the same,reference beinghad to the accompanying drawings, and to the letters of reference marked thereon.

This invention relates to a new and useful improvenient in valves for water-closets, and is suitable ihr either pan or hopper-closets, whereby they are rendered more useful and durable than they have hitherto been; and f l It consists in the construction and arrangement ot' parts, as hereinafter described.l

The drawing represents a vertical longitudinal section of the valve as applied to a pan-closet.

A represents the shell ofthe valve, formed of diierent sections, together with packing secured in the joints, and is fastened to a projecting arm, B, cast on the receiver for that purpose, as seen in the drawing. O is an extension-screw on the spindle E, which is depressed by the arm F ofthe closet-lever, which has its fulcrum at c.

In this manner the spindle E is depressed, and with it the' tube D, which bears on, the inner packing e of the valve f, and drivesthe spindle G,-with the plunger H, into the chamber I.

While the valve is in this position, no water can pass through it. When the pull of the closet is dropped, the spring J lifts the spindle E and tube'Dfrom the packing c, when the water ows'tbrough the tube D andwaterways K K, at its upper end, and through the outlet.

pipe L to the basin, which it washes, and leaves the pan full, ready for use again. A

The stem K oi the lvalve j, extends upward through the tube D, and has ahead on it, that lits, and allows it to slide inthe recess M at the top.

By this arrangement, a slip-connection. is made between the spindles E and G, which admits of the tube D being lifted from the packing c a s uiicient distance to allow the water to passv through thetube, as `previousl y described.

The plunger H, having been depressed or. forced into thechamber I, would be drawn upward by the spring J, but for the following reasons:

The chambersN and I being tilled with water, the

descent of the plunger H causes the water to escape past the elastic washer o, to the upper chamber N.

l Now, before the valve and plunger can ascend again, to close the valve, the displaced water, now occupying thcchamber N, must return to the lower chamber I; but this is prevented by the elastic washer o, andthe water is retained in the chamber, except as it escapes through a vertical channel cut in the side of the plunger, marked p, which permits the water to return gradually, thereby suspending the valve a suicient length ottime to give the requisite wash to the basin.

The valve j, when closed, bears against the paok 1n q.

.glhe length of time the water is allowed to wash depends on the stroke of the valve, which is adjusted by the screw C.

Between the. partition g and the packing q` there is an annular upright strainer, n u, to admit of which the shell of the valve in that portion is enlarged, which forms a jacket or water-passage, o c, to give the water access to the entire surface of the strainer; and by `placing'it in this manner, I have the benefit of a large surface.

By this improvement, impediments in the mater,`

such as sand and gravel, are prevented from getting under the valve-face, and `causing it to leak--a source of great Vtrouble iu ordinary water-closet valves.

The packing q is fitted tightlyaround the tube D,

and prevents any leakage around the tube while the valve is depressed.

To preventV leakage, the upper portion of the tube D is surrounded by a tightly-tinted washer, secured in the screwjoint, as seen at It in the drawing.

h is a'wasteoutlet, to ca iry otf any leakage that may escape past the washer'R.

The face of the tube D is always in such apos'ition with the valve j, that' the pressure of the water alone would close it, if the springwere not'present tokeep the tube raised from its ,seat until the valve closes -agaiust'the packing q.

It will be seen that the principal improvement in this valve consists in lhaving the tube D and valve f sov constructed, that should the spring become defective, the valve .will remain closed, and allow no water to pass, and under no circumstances can it be fastened -open, either by accident or design.

` In applying this valve to hopper-closets, I make use of the dange Y, which is fastened to the iioor in the vusual manner; and the adjustable socket X is used instead of the `screw O. -A rod extends from the -sockt to the seat of the closet, which is hinged, and yields to theweight of the person, and operates the valve in the same manner as previously described.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is-.

The sliding tube D, having ports K K and recess M, in combination with the stem K', having a head, a, iitted to slide in the recess M, to form a slip-joint,

-substantially as described.

In witness whereof, I have hereunto set my hand and seal. Y

W. SMITH. [1.. 8.]
